- -.Claim.: 3' (Cl. 98-45) This invention relates to a ventilator for use in a building such as a home or the like.

The object of the invention is to provide a ventilator or air control mechanism which will permit circulation of cool or heated air to various parts of a building such as a home.

Another object of the invention is to provide a ventilator mechanism which includes a means for recovering waste heat from a furnace or the like which waste heat normally passes up through the flue, the present invention including a control which can be manually set so as to adjust the amount of air circulating through the system.

A further object of the invention is to provide an air ventilating or control mechanism which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout he same.

Figure l is a side elevational view illustrating the air ventilating mechanism of the present invention and showing a wall in section.

Figure 2 is an enlarged side elevational view of the air control mechanism, with parts broken away and in sections.

Figure 3 is a sectional view taken on the line 3--3 of Figure 1.

Figure 4 is a sectional view taken on the line 4-4 of Figure 2.

Figure 5 is a sectional view taken on the line 55 of Figure 3.

Figure 6 is a sectional view taken on the line 66 of Figure 2.

Referring in detail to the drawings, the numeral 10 designates a furnace or the like, and the numeral 11 designates a portion of a wall which may be basement wall. A pipe 12 leads from the furnace 10, and the pipe 12 communicates with a conduit 13 which includes a vertical section 14, a horizontal section 15, and a vertical section 16, the vertical section 16 may lead to a suitable chimney, flue or the like.

The present invention is directed to an air ventilating mechanism which permits recovery of any waste heat which may pass up through the conduit 13, and the air regulating or ventilating mechanism of the present invention includes a hollow housing 17. A conduit 18 may extend through the wall 11, and the conduit 18 is adapted to convey air from outside the building, the conduit 18 being connected to the lower end of the housing 17. A screen 19 may be mounted on the conduit 18 for filtering the air which passes therethrough.

There is further provided a conduit 20 which is connected to the upper end of the housing 17, and for retaining the housing 17 in place, brackets or clamps 21 may be secured to the wall 11 by suitable securing elements 22, Figure 1.

Arranged within the housing. 17 are balfles 23 and 24 to increase the efiiciency of the system. A conduit 25 is connected to the lower end of the housing 17,. and a blower mechanism 26 is connected to the conduit 25. The blower mechanism '26 includes a hollow casing '27 which has a motor 28 connected thereto, and the motor 28 may be connected to a source of electrical energy through the medium of wires 29. A plate '30 is mounted for movement into and out of closing relation with respect to an inlet opening 31 in the casing 27. A manually operable knob 32"is connected to the plate '30 for pivoting the plate 30, and a pivot pin 33 pivotally connects the plate 30 to the casing 27.

From the foregoing it is apparent that there has been provided a ventilating mechanism which can be used for different purposes as for example, it can be used for recovering waste heat. that is ordinarily lost as the flue gases leave a furnace. In use, the housing and its associated parts can be mounted on the conduit 13 as shown in the drawings and ordinarily a certain amount of waste heat travels up the flue and out through the vertical section 16 of the conduit 13 whereby this heat is lost by passing out through the chimney or flue. However, with the present invention the air which enters the housing 17 through the conduit 18 is passed in heat exchange relationship with respect to the section 16 of the conduit 13 so that this cold air will pick up some heat from the flue gases in the conduit section 16 and the air will thus be heated and will pass out through the conduit 20. The air leaving the conduit 20 can be conveyed to any suitable locality as for example to a room in a house to be heated. The blower mechanism 26 can be used for controlling the amount of air which passes through the housing 17. Thus, by manually gripping the knob 32 and pivoting the plate 30, the effective size of the opening 31 can be varied whereby the amount of air entering the inlet opening 31 can be adjusted so that the air passing out through conduit 25 into the bot tom of the housing 17 can be varied as desired. Thus, by opening the plate 30 so as to expose the entire opening 31, an increased amount of air will be blown out through the conduit 25 into the bottom of the housing 17. It will be noted that the upper edge of the baflle 23 is above the top of the conduit 18 so that the air from the conduit 25 will create a suction or vacuum effect whereby increasing the amount of air passing from the blower 26, then the amount of air sucked into the conduit 18 can also be increased. The screen 19 serves to filter out any impurities in the incoming air. The conduit 18 may be arranged in a wall such as the wall of a basement and the outer end of the conduit 18 may communicate with the outside of the building so that fresh air can be withdrawn into the system from outside of the home or in a building. The baffles 24 help to increase the efficiency with which the heating exchange takes place. When the furnace 10 is not being used, during the summer months, the blower 26 can be actuated, so that cool fresh air will be sucked in through the conduit 18 and this cool air will be blown up through the housing 70 then out through the conduit 20 whereby the cool fresh air can be used for cooling rooms or the like or supplying rooms with cool fresh air.

Thus, it will be seen that there has been provided a dual control fresh air ventilator. The device is ruggedly constructed so that it will not readily get out of working order. The device will circulate cool or heated fresh air into rooms and the air is introduced from the outside of the building. In the summer cool fresh air can be introduced in the rooms, and in the winter hot fresh air can be introduced into the house. The device can be readily attached to or detached from the supporting structure.
